采用高功率氙弧灯的光学炉，用浮区法成功地生长了烧绿石Pr_2Hf_2O_7大单晶。通过粉末同步加速器X射线和中子衍射进行结构研究，以建立所产生的材料的晶体结构。单晶的磁性被确定为施加磁场沿沿着不同的晶轴。结果表明，Pr_2Hf_2O_7是一种值得进一步研究的阻挫磁体材料。高质量的晶体使它们成为详细研究的理想选择，特别是使用中子散射技术。
Large single crystals of pyrochlore Pr2Hf2O7 were successfully grown by the floating zone technique using an optical furnace equipped with high power xenon arc lamps. Structural investigations were carried out via powder synchrotron x-ray and neutron diffraction to establish the crystallographic structure of the materials produced. The magnetic properties of the single crystals were determined for magnetic fields applied along different crystallographic axes. The results revealed that Pr2Hf2O7 is an interesting material for further investigation as a frustrated magnet. The high quality of the crystals produced makes them ideal for detailed investigation, especially using neutron scattering techniques.
